translation Dutch appointments+

Hi,

Merry Christmas to you!

In the previous version that I had before upgrading on October 13th, there were language .po and .mo files that I used to translate a great deal of the plugin into Dutch to suit our niche. Unfortunately the update overwrote all that work and offers only a .pot file.
1)Is there any way to get a lang directory with the .po and .mo files so that I can retranslate?
2)can I reupload the translated files after another update of the plugin in the future without causing problems in its function?
3) or is there a way to just get to work with translating with only the .pot file available?

I look forward to your advice..

Cheers
